Ohio radon contractors: territory, leads, and how we work

Radon Connect routes homeowner requests across three Ohio markets — Columbus, Cincinnati, and Dayton — covering Franklin, Delaware, Hamilton, Butler, Warren, Montgomery, and Greene counties.

Ohio is one of the states that genuinely licenses radon mitigation contractors, which makes verification straightforward on both sides: we check your license at onboarding, and homeowners can check it themselves before signing.

Licensing expectations in Ohio

Ohio licenses radon testers, radon mitigation contractors, and radon laboratories through the Ohio Department of Health, and performing mitigation for compensation without that license is not permitted. We verify the mitigation license specifically — Ohio licenses testing and mitigation separately, and a testing license does not authorize installing a system. That distinction is stated on every Ohio market page homeowners read, so expect to be asked for the number.

Territory exclusivity

Territories are assigned at the county level inside each Ohio market: Franklin and the Delaware-Licking territory in Columbus; Hamilton and the Butler-Warren territory in Cincinnati; Montgomery and Greene in Dayton. A qualified homeowner request is shared with no more than three licensed contractors covering that county, and roster size per territory is capped rather than sold to the highest bidder.

How homeowners are qualified before you hear from us

Homeowners complete a multi-step form before a request reaches you: result band, transaction context, timeline, property type, foundation type, and property ZIP resolved deterministically against our Ohio territory list. Dispatch happens at or above 4 pCi/L, or between 2 and 4 inside an active transaction. Ohio’s Residential Property Disclosure Form asks sellers about known radon testing and results, so transaction requests here often arrive with prior test history attached.

Service area requirements

Claim only counties you actually service. Cincinnati hillside housing produces multi-zone designs — cellars, walkout levels, and multiple slab elevations under one roof — that are a genuinely different job from a Mason subdivision retrofit. Dayton’s Beavercreek and Fairborn requests frequently carry PCS deadlines. If your capability or your schedule does not fit a county, leave it off rather than absorbing requests you cannot serve.

How to apply

Send your business name, Ohio Department of Health radon mitigation license number, the counties you serve, and proof of insurance through the contact page. We verify the license against Ohio licensing records before routing anything. No application fee, no monthly charge, no purchased exclusivity — compensation is per referral and disclosed to homeowners on every page.

Ohio contractor questions

I hold an Ohio testing license. Does that qualify me?

Not for mitigation referrals. Ohio licenses testing and mitigation separately, and we route mitigation requests only to businesses holding the mitigation license. If you hold both, say so at onboarding — measurement capability is useful context even though we do not route testing work.

How much of the Cincinnati work is hillside and multi-zone?

A meaningful share. The older neighborhoods built into the Ohio River hills routinely combine a cellar, a walkout level, and a slab addition, and those designs demand diagnostics rather than a template. We flag foundation type in every request so you know what you are quoting before you drive.

What does capped territory mean in practice?

At most three Ohio-licensed contractors per county receive a qualified request, and roster size per territory is limited. We will not sell you sole rights to Franklin County, and we will not quote you a lead-volume figure we have not measured.

How the network operates

Apply

Contractor onboarding is handled directly rather than through the homeowner quote form. Reach us through the contact page with your business name, your Ohio credential number, and the counties you serve — the application page lists exactly what to send. See how we work for the full referral model, including how we are compensated.
